What could possibly go wrong?
from Science World Report:
In the antimatter hall, four collaborations – ATRAP, ALPHA, ASACUSA and AEGIS – trap antiprotons using Penning traps, to make antihydrogen for experiments. But in most of today’s set-ups, more than 99% of the antiprotons from the AD are lost through the degrader foils that decelerate the particles from their ejection energy down to the energy suitable for trapping (around 5 keV).
